Gabor Horvath 26e672e4e0 [cxx-interop] Fix runtime crash passing FRTs as const FRT*
We should pass foreign references as Direct_Unowned calling convention,
this happened for non-const pointers. Unfortunately, we passed the const
variants as Indirect_In. This resulted in SILGen trying to insert a
non-sensical conversion. This triggered an assertion failure or a
miscompilation depending on how the compiler was compiled.
